GLASGOW — In the first doping scandal of the Commonwealth Games, a 16-year-old female Nigerian weightlifter was provisionally suspended Tuesday after testing positive for banned substances.

Chika Amalaha tested positive for the diuretic amiloride and masking agent hydrochlorothiazide — both banned by the World Anti-Doping Agency — after winning the 53-kilogram weight class last Friday, games officials said.

She’s the first athlete to test positive during the games, which opened last Wednesday night.

Amalaha asked for the backup “B” sample to be tested, which will happen in London on Wednesday. If that sample also comes back positive, she will be stripped of her medal.

“It sends a strong message to anybody in any sport that if you go down the path of doping, any substance to enhance performance, they will be caught,” Commonwealth Games Federation chief executive Mike Hooper said.

It’s the second Commonwealth Games in a row that Nigeria has been in the doping spotlight. Four years ago in New Delhi, three of the four doping cases involved Nigerian runners, including women’s 100-meter gold medallist Osayomi Oludamola.

Meanwhile, the king of the track met with British royalty in the athletes’ village.

Prince William and his brother, Prince Harry, met Jamaica’s Usain Bolt, the multiple Olympic sprint champion and world record-holder over 100 and 200 metres.

Harry posed for a photo with Bolt, who is running in the 4×100 relay this week. William was reported to have jokingly said to Bolt as he approached him: “What’s all the fuss about?”

Elsewhere at the games on Tuesday:

CANADIANS, KIWIS 1-2: Catharine Pendrel of Canada, the 2011 mountain bike cross-country world champion who finished ninth at the 2012 London Olympics, won gold in the women’s cross-country race at the Cathkin Braes Country Park course in Glasgow. Her Canadian teammate Emily Batty took the silver, with Rebecca Anderson of Australia earning the bronze. “We trained well as a team,” Pendrel said. “I knew from training and the nationals that Emily was on fire, so I’m proud she got silver.” In the men’s race, New Zealanders were 1-2, with Anton Cooper beating Samuel Gaze by just three seconds for gold. Australian Daniel McDonnell took the bronze.

SHOOTING FOR GOLD: Australian shooters won both golds on offer in early events, with English and Indian competitors taking the minor medals. Adam Vella defeated Aaron Heading of England in the men’s trap final, and Manavjit Sandhu of India took the bronze. David Chapman of Australia took gold in the 25-meter rapid-fire pistol, India’s Harpreet Singh took silver and Kristian Callaghan of England earned the bronze.
